The Jäger HARL 3618+ is an 18-inch actuator for motorising a prime focus satellite dish up to 180 cm. It is designed for installations where a separate positioner moves the dish between satellite positions.
The actuator produces linear movement: as its arm extends or retracts, the dish rotates on its motor mount. The built-in reed sensor sends position pulses to the positioner, allowing it to track dish movement and return to stored satellite positions.
With an 18-inch stroke, approximately 45.7 cm, and a 36 V DC motor, the HARL 3618+ suits larger motorised satellite installations. It can be used for a new system or as a replacement actuator when the mounts, movement geometry and positioner are compatible.
✅ Product Benefits
- Motorises a prime focus dish up to 180 cm
- Allows movement between satellite positions
- 18-inch actuator stroke
- Reed sensor provides position feedback
- 36 V DC motor for a suitable external positioner
- Suitable for new installations or compatible replacements
- Limit switches restrict movement at the end positions
🎯 Ideal For
- Prime focus satellite dishes with a motor mount
- Satellite dishes up to 180 cm
- Receiving several satellite positions with one dish
- Existing systems with a separate actuator positioner
- Replacing a compatible older 18-inch actuator
🔧 Connection and Operation
Mount the actuator between the fixed and moving points of the dish assembly. Connect the motor and reed-sensor wires to a compatible external positioner. The positioner powers the motor and counts the sensor pulses to track the dish position.
After installation, set the movement range and end limits. Make sure the dish can move freely in both directions without being driven into a mechanical stop.
A separate positioner is required and is not included.

📺 Satellite Positions and Reception
With a compatible positioner, the actuator can move a prime focus dish between several satellite positions. The available range depends on the dish location, motor mount and system setup.
The actuator moves the dish; the LNB, receiver and other reception equipment are selected separately.
